PSG has now claimed the prestigious trophy on fourteen different occasions.
The Parisian giants required a dramatic leveler followed by a perfect spot-kick decider to overcome their arch-rivals in Kuwait and secure a fourth straight Trophee des Champions victory.
The European champions appeared to be sailing towards a straightforward triumph in the showdown featuring the Ligue 1 winners and the French Cup holders after Ousmane Dembele opened the scoring in the opening stages.
Yet, Marseille struck two times late to seize a shock lead. Initially, Mason Greenwood converted from the spot-kick, before Willian Pacho inadvertently directed the ball into his own net for an own goal.
In a breathtaking twist of events, Goncalo Ramos grabbed a vital leveler in the dying seconds to send the match into a penalty shootout. PSG goalkeeper Chevalier then stood as the key figure, stopping decisive attempts from O'Riley and Traore.
From the spot, Ramos, Vitinha, Nuno Mendes, and the young talent all scored successfully for PSG to complete a convincing shootout win.
The record champions Paris Saint-Germain, who faced last season's Ligue 1 second-placed team Marseille after completing a domestic double, have now lifted this trophy for the 12th time in the last 13 seasons.
